Emily Ratajkowski is at it again with another girl-crush-worthy moment on Instagram.

No caption was needed for the 24-year-old's latest IG photo, which shows the model flaunting her killer bikini body — complete with a flash of underboob. Wearing a red patterned bikini with strategically placed cut-outs, Emily went makeup-free for the racy pic.

"It's so important that we let women express their sexuality and share their bodies however they choose," the Gone Girl star tweeted. She ended her message with a quote from feminist activist Emma Goldman.

"Merely external emancipation has made of the modern woman an artificial being. Now, woman is confronted with the necessity of emancipating herself from emancipation, if she really desires to be free."
